IMPROVEMENT IN MUSICPORTFOLIOS.

Specification forming part of Letters Patent No. 133L613, dated January7, 1873.

To all whom it mag concern:

Be it known that I, FRANK CHRISTIAN SOHUMANN, of the city, county, andState of New York, have invented a new and useful Improvement inCombination Music Back and Portfolio, of which the following is aspecification: 7 1n the accompanying drawing, Figure 1 represents anopen portfolio to which my improvement has been applied; and Fig. 2 is adetail sectional view of the same adjusted for use as a music-rack takenthrough the line or m, Fig. 1.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish animproved portfolio forsheet-music, which shall be so constructed as to adapt it for use as arack for supporting apiece of music while being used; and it consists inthe combination of a bracket with the side plates of an ordinaryportfolio, as hereinafter more fully described.

A and 13 represent the two side plates of a music-portfolio, the inneredges of which are connected by a spring back, (3, about theconstruction of which there is nothing new. To the middle part of one ofthe side plates, as A, of the portfolio is hinged the edge of atriangular plate, D. The inner edge (1 of the sheets of music and firmlysupport the said plate A. When the portfolio contains but little music,or is empty, the plate D will rest upon its free angle, as shown in Fig.2. When the portfolio is to be closed the plate D is turned down uponthe plate A, to which it is hinged, as shown in Fig. 1.

It will be observed that when the portfolio is used as a music-rack thelower edges of the piece of music rests upon its spring back 0, whichserve as a ledge to keep it from slipping down.

I have described the bracket D as made in the form of a triangularplate, but its form is entirely immaterial so long as it is connectedwith one plate or leaf of a music-portfolio, and so arranged as to restupon the other plate or leaf, or upon the pieces of music placed in saidportfolio to support the said leaf or plate in an inclined position.

Having thus described my invention, I claim as new and desire to secureby Letters Patent The combination of a bracket, D, with the spring back0 and side plates A B of a musicportfolio, in such a way that it maysupport one of said side plates in an inclined position to adapt it toserve as a music-rack, and may be turned down out of the way when notrequired for use to allow the portfolio to be closed, substantially asherein shown and described.
